Native VLAN ID configuration on the reth interface

Configuring the native VLAN ID on the redundant Ethernet (reth) interface enables the logical interface whose VLAN ID matches the native VLAN ID that is configured for that interface to accept untagged packets as well as tagged packets. Using the same logical interface with the native VLAN ID enabled ensures that any packet going out of that interface does not have a tag attached. Packets can be outbound control packets or transit data packets.
